[scikit-learn] Fitting Lognormal Distribution

[Startup Hire]

Hi,

(1) - Thanks. will do that

(2) - I am fitting the distribution for 2 different set of values.. I will
find the distribution as mentioned by you in (1).. But, now having 2
curves, how do i find the meetings point(s) ?

Regards,
Sanant
